In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.

crit. speed

Runner resonant frequency calculated taking into account the additional support and damping caused by the effect of the fluid in the impeller

crit speed (wet)

Rotor resonant frequency calculated assuming that the rotor is supported only in the bearings and that the bearings have infinite stiffness

crit speed (dry)

The specific speed (ns) is a characteristic coefficient derived from the similarity conditions which allows a comparison of impellers of various pump sizes even when their operating data differ (flow rate and head at best efficiency point, rotational speed)

specific speed

Suction specific speed nss as defined in EN 12723 is used to classify the suction characteristics of centrifugal pumps. It is derived from the similarity conditions for cavitation and calculated on the same formal basis as the specific speed ns.
